The following are some of the best techniques for improving data quality in big data:
Deploy data administrators to different business units and build processes for data and data element review and verification.
To set up data governance practices, you'll need executive support.
Describe the data standards, terminology, and controlled vocabularies for business glossaries.
Incorporate data validation and frameworks into current processes and structures.
Form a cross-functional data governance team of business users, analysts, data custodians, data architects, statisticians, and application developers.
Establish solid governance systems, which include data governance, proactive management, and data evaluations on a regular basis.
Promote the use of controlled vocabularies developed by institutions such as the International Organization for Standardization, the World Health Organization, and the Medical Dictionary for Regulatory Activities.
Wherever conceivable, avoid data duplication by merging collections of large data through connections to other systems.
Build effective master data management practices to ensure that an organization's product or customer data is defined in a uniform and consistent manner.
